  Embodiments of the present invention will be described below with reference to the drawings.

[Luminescent sheet]
First, the light emitter sheet used in the embodiment of the present invention will be described.
The phosphor sheet 1 used in the embodiment of the present invention is a base sheet made of a thin resin sheet having translucency (transparent is suitable but may be translucent). A luminous layer containing a luminous agent is formed on a sheet in a laminated form. The luminescent sheet 1 has translucency as a whole.

Various methods can be employed to form the phosphorescent layer, and the following methods can be employed as suitable methods.
That is, a liquid or gel synthetic resin such as urethane, epoxy, acrylic, etc. is mixed with a phosphorescent agent, a coloring pigment, a plasticizer, etc. to form a paste, and this is applied to the surface of the base sheet (for example, a roll). Coating) to integrate the two.

  Hereinafter, an embodiment of the present invention will be described based on the phosphor sheet 1 manufactured as described above. However, the phosphor sheet 1 is merely an example, and the configuration according to the “luminant sheet” of the present invention is applied. It is not limited only to what consists of. For example, a phosphorescent agent may be mixed into the resin sheet itself.

[First Embodiment]
FIG. 1 is a front view of an entrance door using a light emitting device according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line AA in FIG. In FIG. 2, the upper side toward the paper surface is the outdoor side, and the lower side is the indoor side (this also applies to FIGS. 3, 5, and 7 (all show cross-sectional views) described later).
1 and 2, the entrance door 2 is provided with a small window 3 having a vertically long slit shape. The small window 3 includes a laminated glass member G described later. As shown in FIG. 2, the laminated glass member G includes a glass receiving groove 7 formed by a flange 3 a provided on the door main body and a pressing edge 5 for glass presser that is detachably engaged and fixed to the flange 3 a. The peripheral edge is fitted and fixed to the front door 2.

  The laminated glass member G includes rectangular glass plates G1 and G2 on the outdoor side and the indoor side, respectively, and the luminous body sheet 1 is sandwiched and integrated between them. The light emitting sheet 1 is formed in a size smaller than the mating surfaces of the outdoor and indoor glass plates G1 and G2, and when sandwiched between the glass plates G1 and G2, the laminated glass member G A concave groove 6 is formed on the facet. As an example of the dimension of the groove 6, the width × depth can be 3 mm × 3 mm.

  The laminated glass member G is installed in the glass housing groove 7 of the bowl 3a with a clearance D secured, and the peripheral edge of the outdoor side thereof is bonded and fixed to the bowl 3a with a caulking agent 8. On the other hand, the indoor peripheral edge is fixed to the collar 3a by a presser bead 9 that is detachably press-fitted between the indoor glass plate G2 and the pressing edge 5.

  A strip-shaped light source 10 is attached to the concave groove 6 between the glass plates G1 and G2 on the outdoor side and the indoor side. The strip-shaped light source 10 includes a strip-shaped substrate 10a provided with a plurality of LEDs 10b (for example, LED chips) along the longitudinal direction thereof. In the present embodiment, the strip-shaped light source 10 is arranged in a row at a fixed interval on the flexible strip-shaped substrate 10a. LED 10b is arranged and mounted. However, it is not necessarily limited to the thing of this structure. In addition, as a base member which arrange | positions several LED10b, it may replace with a strip | belt-shaped board | substrate and you may use what gave insulation coating to the thin plate-shaped copper plate hoop material.

Such a strip-like light source 10 is applied to the small edge surface of the laminated glass member G with its longitudinal direction along the longitudinal direction of the concave groove 6, and the laminated glass member G is pressed into the clearance D behind the laminated glass member G. Closely fixed to the facet of At this time, each LED 10 b is accommodated in the concave groove 6.
When removing the strip-shaped light source, the laminated glass member G can be easily removed by removing the spacer 11.

  The belt-like light source 10 may be provided in an endless manner so as to go around the four sides of the laminated glass member G, or may be arranged to face each other so that the LEDs 10b face each other on the two opposite sides. Furthermore, you may provide only in two adjacent sides of four sides so that it may become L shape or reverse L shape. The band-like light source 10 in the present embodiment is configured to switch the emission color by operating a changeover switch (not shown).

The small window 3 of the present embodiment configured as described above has the following effects.
That is, the small window 3 of the present embodiment can produce a fantastic landscape by emitting light during the daytime or evening when the illuminant sheet 1 stores natural light during the daytime and the surroundings become dark.
In addition, when the LED 10b is energized, the LED light emitted from the small edge of the light emitter sheet 1 is diffusely reflected by the particulate luminous agent and the color pigment contained in the light emitter sheet 1 to make the glass surface brighter. Can be dyed.
Furthermore, since the LED emission color can be changed by operating a changeover switch (not shown), a beautiful landscape rich in changes can be produced.
Furthermore, since the light emitter sheet 1 continues to accumulate light even while the LED 10b is turned on, light emission can be continued even after the LED 10b is turned off.

In order to remove the strip light source 10 for repairing / replacement of the aged LED 10b, first, the presser bead 9 is removed, and then the pressing edge 5 is pushed toward the indoor side glass plate G2 to engage with the flange 3a. Unscrew and remove. Then, since the clearance D is exposed, the strip light source 10 can be easily removed by pulling out the spacer 11. In the meantime, since the glass plate G1 is being fixed to the eaves 3a with the caulking agent 8, the laminated glass member G does not fall off and can be safely operated.
When the replacement / repair operation of the LED 10b is completed, the assembly operation may be performed in the reverse procedure.

  In addition, since it is necessary for the light-emitting body sheet 1 to have translucency so that natural light can permeate | transmit, as a color, the thing of a pale color of milky white, blue or green is preferable. For this reason, the color pigment used together with the phosphorescent agent is white, blue or green that enhances the luminescent color (blue or green is the basic color) of the phosphorescent agent, and the amount of mixture is reduced and the translucency is excessively lost. It is preferable not to do so.

[Second Embodiment]
The vertically long slit-shaped small window 3 of the first embodiment is narrow with a width of about 10 to 20 cm. However, in the case of a wide window, the irradiation light of the LED 10b is difficult to reach the center of the glass. There may be an inconvenience that the difference in brightness between the peripheral portion and the central portion becomes too large.

  Therefore, in the second embodiment shown in FIG. 3, the phosphor sheet sandwiched between the two glass plates G1 and G2 is made into two layers 1a and 1b, and a transparent thin plate resin 12 as a light guide layer therebetween. (For example, a thin plate resin having a thickness of 1 to 2 mm). Since other configurations are substantially the same as those of the first embodiment, the same members as those of the first embodiment are denoted by the same reference numerals in FIG.

  In this 2nd Embodiment, the said thin plate resin 12 functions as a light guide layer, and while delivering the LED light irradiated from the edge of the laminated glass member G to a distant place, inside and outside light emitter sheet | seat 1a * 1b Since it can irradiate more uniformly from a back surface, there exists an effect that surface emission can be performed uniformly over a wide range.

The thin plate resin 12 is preferably disposed on the entire surface of the glass, but it is also possible to dispose a thin resin around the glass surface. However, if the thin resin 12 is stretched over the entire surface, the strength of the laminated glass member G itself can be strengthened, so that an effect of being able to resist an external pressure such as wind pressure can be achieved.
In addition, as a light guide layer, you may use not only the thin plate resin 12 but a glass thing, and what is called a light guide plate.

[Third Embodiment]
In the embodiment of the double glass type as described above, a configuration in which the entire glass surface is covered with the phosphor sheet 1 that is slightly inferior in transparency is general (however, the entire surface is not necessarily required), but the present invention. Can also be applied to so-called multi-layer glass, that is, a structure in which an air layer (hollow layer) is hermetically formed between two glasses for the purpose of heat insulation and sound insulation.
The third embodiment of the present invention shown in FIGS. 4 and 5 has such a configuration.
Hereinafter, a third embodiment of the present invention will be described. In addition, the same code | symbol is attached | subjected to the member which has the same function or structure, and description is abbreviate | omitted.

  As shown in FIG. 4, the entrance door 20 according to the third embodiment is provided with a glass part 30 over a wide range of the door body, and a gutter 3 a is provided around the glass part 30.

  In the third embodiment, the phosphor sheet 1 is provided on the inner side (inside the room) of the peripheral edge of the outdoor glass plate G1, and from the outside, the phosphor sheet has a width d from the outside of the outer surface of the flange 3a. 1 is visually recognized. A transparent synthetic resin light guide layer 12 that is formed in a different shape in an angle shape is closely arranged inside the light-emitting body sheet 1, and a strip-like light source 10 is detachable on the small edge side of the laminated glass member G. The recessed groove 6 fitted to the is formed. Further, a desiccant pocket 15 for storing the desiccant is provided between the light guide layer 12 and the indoor side glass plate G2. A sealing material 16 is filled on the small mouth side of the desiccant pocket 15, and an air layer (hollow layer) 17 between the glass plates G1 and G2 is hermetically sealed from the outside air.

  The laminated glass member G configured as described above has a soundproofing function, a heat insulating function, and a dew condensation preventing function for the hollow layer 17 similar to those in the past as a multilayer glass.

The entrance door 20 incorporating the multi-layer glass G having the above structure can emit light only at the peripheral edge along the ridge 3a by light emission of the illuminant sheet 1, while the portion near the glass center away from the ridge 3a is transparent. Since a simple glass structure is maintained, it is possible to produce an appearance that is different from that when the illuminator sheet 1 is stretched over the entire surface.
The light guide layer 12 is not essential and may be omitted.

[Fourth Embodiment]
6 and 7 are drawings showing a fourth embodiment of the present invention.
As shown in FIG. 6, the entrance door 40 according to the fourth embodiment of the present invention is provided with a glass part 50 over a wide range of the door body, and a gutter 3 a is provided around the glass part 50. This is the same as in the third embodiment. However, the specific configuration of the glass part 50 is different.

In the fourth embodiment, as shown in FIG. 7, the phosphor sheet 1 (that is, liquid or gel transparent synthetic resin such as urethane and epoxy is mixed with a luminous agent, a color pigment, a plasticizer, and the like. Instead of the phosphor sheet 1) in which a phosphorescent layer is formed by applying the paste on the surface of the base sheet, a gel containing a phosphorescent agent on one surface of the base sheet 100a made of a polyester film. The phosphor sheet 100 having the phosphorescent portion 100b formed by adhering the paste in the form of dots is used.
That is, the other surface of the phosphor sheet 100 having such a configuration (the surface on which the dot-shaped phosphorescent portion 100b is not formed) is attached to the inner surface of the outdoor glass plate G1, and the LED irradiated from the strip light source 10 By making the light rays diffusely reflected by the dot-shaped phosphorescent portion 100b, it is possible to produce a fantastic landscape in which light-emitting dots dyed in the LED emission color are scattered on the appearance.

In FIG. 7, the light guide layer 12 has a thick (for example, 3 to 4 mm) angle shape and is bonded to the desiccant pocket 15. The point that the air layer (hollow layer) 17 is hermetically formed between the two glass plates G1 and G2 is the same as in the third embodiment.
Moreover, the point which can remove the strip | belt-shaped light source 10 by removing the spacer 11 is the same as that of the above.

In the fourth embodiment, as shown in FIG. 6, the dot density of the phosphorescent portions 100b is increased in the upper part. As a result, it is possible to reduce the incidence of sunlight during the day.
On the other hand, although not shown, a blinding effect can be achieved by increasing the interstitial density of the dot-like phosphorescent portions 100b in the lower part.
Thus, in this embodiment, according to the use thru | or required quality of the window glass or door glass to apply, the dot density of the dot-shaped luminous storage part 100b can be changed for every site | part. However, it is needless to say that the dot density of the dot-shaped phosphorescent portion 100b may be made uniform.

  As mentioned above, although embodiment of this invention was described, this invention is not necessarily limited to the said embodiment. In each of the above embodiments, the present invention is applied to the entrance door glass. However, the present invention may be applied to pure window glass. The present invention can be implemented with various modifications within the scope of the claims.
